PhoneGap has a plugin-based architecture. Each device-specific feature is a plugin, which consists of javascript and native sides.

Js side should be as cross-platform as possible, whereas native side can be implemented only once, for 1 device. Nevertheless built-in plugins are developed for all of the most popular platforms, so no need to reinvent the wheel.

This architecture, together with open source code, not only allows a developer to fix their bugs, but also allows them to tweak their plugins for as per requirements. Also, a developer can build his own plugin, and support any platform of his choice.

Mobile developers use PhoneGap because it allows them to have a common codebase for all their application code. It doesn’t force developers to reinvent the wheel every time they move from platform to platform.

Building applications for each device–iPhone, Android, Windows Mobile and more–requires different frameworks and languages.

One day, the big players in mobile may decide to work together and unify third-party app development processes.

Until then, PhoneGap will use standards-based web technologies to bridge web applications and mobile devices. Plus, because PhoneGap apps are standards compliant, they’re future-proofed to work with browsers as they evolve.

PhoneGap is an open source implementation of open standards. That means developers and companies can use PhoneGap for mobile applications that are free, commercial, open source, or any combination of these.

Mobile market is huge with bunch of opportunities. At the same time it is really painful experience for the developers to make an application reach to the wider audience.

There are multiple platforms like android, iPhone, Blackberry, windows comes with lot different capabilities. Every platform uses different programming language syntax and different distribution process.

As the programming platforms are different, developing an application requires putting the separate development effort for different platforms.

PhoneGap was donated to the Apache Software Foundation (ASF) under the name Apache Cordova. Through the ASF, future PhoneGap development will ensure open stewardship of the project. It will remain free and open source under the Apache License, Version 2.0.

PhoneGap is an open source distribution of Cordova. Think about Cordova’s relationship to PhoneGap like WebKit’s relationship to Safari or Chrome.

PhoneGap is a mobile application development framework, based upon the open source Apache Cordova project.It allows you to write an app once with HTML, CSS and JavaScript, and then deploy it to a wide range of mobile devices without losing the features of a native app.

PhoneGap Build is a cloud-based service built on top of the PhoneGap framework.

A hybrid application is one that has features of both a web application and a native application. Certain features, such as Image Capture, NFC or Android OpenAccessory, may be implemented natively since there is currently no way to do this in JavaScript. But the application logic and the UI are implemented using web technologies to allow for a consistent and unique user experience across devices.

A PhoneGap application may only use HTML, CSS, and JavaScript. However, you can make use of network protocols (XmlHTTPRequest, Web Sockets, etc) to easily communicate with backend services written in any language. This allows your PhoneGap app to remotely access existing business processes while the device is connected to the Internet.

PhoneGap is an open source implementation of open standards and FREE. That means developers and companies can use PhoneGap for mobile applications that are free, commercial, open source, or any combination of these.

Back-ground processing: Large number of application depends on background thread while PhoneGap API are built using JavaScript which does not support multi-threaded and hence does not support back ground processing

Advanced graphics: Apps that use advanced graphics can be accessed explicitly by third party libraries, which can be best done natively

Complex business logic: Number of complex business app can be accessed better with a native code

Access advanced native functionality: Number of native API’s are not supported by PhoneGap’s API

PhoneGap: It is a framework for mobile application development, built upon the open source Apache Cordova project. It permits you to write an app once with CSS, JavaScript, HTML and then deploys it to a broad range of mobile devices without losing the features of a native app.

PhoneGap Build: It is a cloud-based service built on top of the PhoneGap framework.

The most fundamental differences between AIR and PhoneGap is that you build AIR applications using tools rooted in the Flash Platform, and you can develop PhoneGap application using HTML, CSS and JavaScript. AIR applications use the AIR runtime, it enables you to have a single code base, with the exact similar expected behavior through all supported platforms. PhoneGap applications execute inside of the native web browser component for each supported platform. For separate platform, PhoneGap may behave differently.

PhoneGap applications can be architect, in the same way, like other mobile web services. The main difference is that the initial HTML assets are available locally, instead of a remote server. The PhoneGap application loads the initial HTML which can request resources from a server or from the local environment. PhoneGap also supports the single page web experienced model.
